G.soak (Guarantee Soak) - Honeywell DCP551 Mark ΙΙ User Manual

G.SOAK (Guarantee soak)

G.SOAK on/off state, type and G.SOAK width is set by the segment. G.SOAK are of
three types: segment start point, segment end point and the entire segment.
G.SOAK time is set using the variable parameter
and PV triggers a G.SOAK wait which narrows the distance between SP and PV to guar-
antee the segment execution time. G.SOAK operates not only on SOAK but also on
RAMP segments.
Note, however, that in FAST mode a G.SOAK setting does not trigger a G.SOAK wait.
G.SOAK can be cleared with an external switch input. The following types of clearing
conditions can be selected using setup data setting
(1) G.SOAK is cleared when an external switch contact is set to on or when PV meets
the G.SOAK clearing conditions.
(2) G.SOAK is cleared when an external switch contact is set to on and PV meets the
G.SOAK clearing conditions.
• G.SOAK at start of segment
PV and SP are compared at the beginning of the segment. The segment starts when
the absolute value of the difference continues beyond the G.SOAK time and becomes
narrower than G.SOAK width.
A G.SOAK wait state continues until these conditions are met which is announced by
the flashing of the linear LED on the left of the profile display.
The operating condition is the same as HOLD at the beginning of a segment (time =
0).
